Abstract
The paper deals with the application of a probabilistic approach for the formation of an electric traction load graph in the simulation modeling of a traction power supply system. The method based on the application of a universal leveling function based on the gamma distribution is chosen as the basic one. The estimation of the approximation efficiency was performed using the Kolmogorov criterion. It is shown that to set the traction load of a single train on sections with a relatively simple track profile, it is possible to use the specified method with gamma distribution parameters determined through the load current efficiency coefficient. Based on the author's model, a two-variant simulation of the traction power supply system for the actual and probabilistic traction load schedule was performed in the SimInTech software package; at the same time, almost identical results were obtained. This allows us to say that a probabilistic graph can be used instead of a real graph to determine the consumption and loss of electricity in the electric traction network. The application of this method is shown. it is deemed that the traction load of the feeders of the contact network requires correction of the parameters of the gamma distribution based on iterative calculation methods.
